The Nike ISPA Flow 2020 SE ‘Black Iron’ highlights neutral tones on a winterized version of the lightweight, summer-ready original. Whereas the original ISPA Flow 2020 featured a synthetic and mono mesh build, this pair opts for grey quilted textile with areas of zoned insulation marked in black. Details include pull tabs at the tongue and heel, a cinched drawcord around the collar, and circular perforated suede inserts at the quarter panel and back heel. Responsive cushioning comes courtesy of a solid white foam midsole, supported by translucent rubber pods under the forefoot and heel.
